Kotetsu, Teru, and Hina are childhood friends.
They have lived in the neighborhood since they were little and they played together regardless of gender, but as Kotetsu got older, he secretly started to fall in love with Hina.
Kotetsu feels inferior to the positive relationship between Teru and Hina compared to the negative Kotetsu, and since Hina talks happily with Teru, Kotetsu thinks that Hina is interested in Teru. As she thought, the person Hina had feelings for was actually Kotetsu.
Hina, who is tired of Kotetsu’s shyness, confesses her feelings, but the three of them are still at a crossroads in their lives, and before it’s too late, time cannot be turned back, so that there are no regrets left. A sweet and sour youthful love story of three people living together.
